Definitions
- the present invention relates to the use of Hydroxycarbamide (HC) for attenuating and / or delaying the extension of non-capillary perfusion, a cause of irreversible visual decline in patients with central retinal vein occlusion (CRVO). ).
- HC Hydroxycarbamide
- CRVO central retinal vein occlusion
- Retinal vein occlusions include central retinal vein occlusions (CRVO) and retinal vein occlusions (RVOs), whose mechanisms, prognosis, and treatments differ (Pierru A et al., EMC - Ophthalmology, 21- 240- E15, 2015).
- OVCRs differ from OBVR by their more severe prognosis, the mean age of onset (10 years younger), and the existence of familial cases.
- OBVR occur almost constantly at the level of an arteriovenous cross (suggesting the involvement of a local process in its pathophysiology), whereas, in the case of CRVO, the localization of venous obstruction is variable and its unknown mechanism.
- the prevalence of CRVO is about 5 times lower than that of RBVs.
- OVCR can also be distinguished from occlusions of the central artery of the retina (OACR), the latter resulting most often from cardiac or vascular embolism.
- OACR central artery of the retina
- hypotheses evoked involve endothelial cell edema, endothelial apoptosis, leukocyte obstruction, local thrombogenesis or haemorrheological disorders (especially erythrocyte deformability and aggregation).
- endothelial cell edema endothelial cell edema
- endothelial apoptosis leukocyte obstruction
- local thrombogenesis local thrombogenesis
- haemorrheological disorders especially erythrocyte deformability and aggregation.
- the therapeutic attitude is limited to administering locally (Le., In the vitreous cavity of the eye) anti-VEGF antibodies or corticosteroids and / or to locally perform a retinal photocoagulation (Glanville J et al., BMC Ophthalmol 2014; 14: 7).
- This local administration is painful for the patient, who must return to the hospital at regular intervals for intravitreal injection.
- this operation is invasive, since the needle must cross the conjunctiva and the sclera in the ocular cavity located behind the lens. It can only be performed by a doctor, under strictly controlled hygiene conditions, which restricts his access to patients who can move to the centers equipped for this operation.
- this surgical procedure can generate possible complications: intraocular infection (which can occur, as in any puncture or surgical procedure, despite the rigorous precautions of asepsis), intraocular hypertonia (elevation intraocular pressure), accidental lens injury, or retinal detachment.
- intraocular infection which can occur, as in any puncture or surgical procedure, despite the rigorous precautions of asepsis
- intraocular hypertonia elevated intraocular pressure
- accidental lens injury or retinal detachment.
- retinal detachment although relatively effective in suppressing neovascular proliferation, none of these local treatments can prevent the extension of the retinal non-perfusion surface, which is the cause of retinal ischemia and its blinding complications ( macular atrophy, neovascularization, retinal / intravitreal hemorrhages, neovascular glaucoma).
- the present inventors demonstrate here that it is possible to significantly reduce the extension of the retinal non-infusion surface by administering to patients suffering from CRVO, and in particular those suffering from a recently diagnosed CRVO (Le., Since less than one month) and therefore in full progression, an initial dose of 20mg / kg / day oral hydroxycarbamide (HC) ( Figures 1 and 2).
- HC oral hydroxycarbamide
- the present patent application relates, in a first aspect, to hydroxycarbamide for its use for treating, systemically, patients suffering from CRVO.
- hydroxycarbamide can be used in these patients for:
- ocular macular thickness 100 ⁇ , preferably 200 ⁇ , even more preferably 300 ⁇ after 3 months of treatment, and / or
- Hydroxycarbamide (Chemical formula: CH 4 N 2 0 2 , hydroxylated analogue of urea - otherwise known as hydroxyurea or HU) was synthesized in Germany in 1869 by Dressier and Stein but it was not until 1928 that it was administered to animals with blood abnormalities such as leukopenia, macrocytosis and anemia. It was not until 1963 that Stearns et al. show that the hydroxycarbamide can be active against mouse leukemia L1210, and then many clinical studies have demonstrated its anti-tumor action in humans. Some of these studies have shown efficacy in the treatment of solid tumors such as malignant melanoma, refractory ovarian cancer, carcinoma of the head and neck, renal or bladder carcinoma. But the emergence of new, more effective treatments for these tumors and the low response rate have now relegated HC after other lines of treatment and still in combination with other chemotherapies.
- HC retains its interest in therapeutic management: ⁇ Myeloproliferative syndromes such as polycythemia vera (PV), essential thrombocythaemia (TE), myeloid splenomegaly or chronic myeloid leukemia (the HYDREA ® is then administered).
- HC is a specific inhibitor of the S phase of the cell cycle. It inhibits ribonucleotide reductase (RR) which transforms ribonucleotides into deoxyribonucleotides.
- RR ribonucleotide reductase
- This enzyme which is produced in a very small amount, causes by its inhibition a decrease in the production of precursors of the DNA. This effect is dose-dependent and also correlates with the duration of drug exposure in most mammalian cell cultures without major side effects. This property is the one mainly used in the treatment of myeloproliferative syndromes.
- SIKLOS® symptomatic sickle cell disease
- HC is today the only active ingredient that changes the course of sickle cell disease.
- Steinberg et al Steinberg MH et al., Am J Hematol, 2010; 85: 403-8 shows that patients who have received HC treatment have a mortality rate of 40% compared to patients who did not receive HC.
- red blood cells (RBCs) of OVCR patients do not present the same abnormalities as GRs of patients suffering from sickle cell disease or myeloproliferative syndromes.
- most adhesion molecules are normally expressed on the surface of RBCs of OVCR patients (Wautier MP et al., Thromb Haemost 201: 9: 1049-55), which is not the case for GR patients with sickle cell disease or myeloproliferative syndromes (Colin Y et al., Curr Opin Hematol 2014; 21: 369).
- endothelial cells of microcirculation of different tissues have distinct and characteristic gene and protein expression patterns (Chi JT et al., PNAS 2003; 100: 10623-8).
- the patients treated (or to be treated) only suffer from OVCR.
- myeloproliferative syndrome is intended to mean the following diseases: primary polycythemia vera (PV), essential thrombocythaemia (ET), myeloid splenomegaly, chronic myeloid leukemia (CML) .
- PV primary polycythemia vera
- ET essential thrombocythaemia
- CML chronic myeloid leukemia
- patients treated (or to be treated) in the context of the invention do not suffer from essential thrombocythemia.
- cancer means any type of solid cancer (such as malignant melanoma, refractory ovarian cancer, carcinoma of the head and neck, renal or bladder carcinoma). or blood (such as leukemias).
- patients treated (or to be treated) in the context of the invention do not suffer from glaucoma.
- the patients treated (or to be treated) in the context of the invention are preferably adults (men or women) aged at least 45 years. Due to the very low toxicity of HC, including in the elderly, there is no maximum age to be treated by the treatment of the invention.
- patients treated (or to be treated) within the scope of the invention have been diagnosed with CRVO for less than one month.
- the symptoms of OVCR in said patient appeared less than a month before said administration.
- the retinal non-perfusion surface in these patients then increases very rapidly, by approximately 30% in 15 days, which can lead to retinal ischemia and, ultimately, blindness (Singer M et al., Retina 2014; 1736-42, Spaide RF et al., Retina 201: 31: 829-37).
- OVCR ophthalmological examinations
- OCT optical coherence tomography
- OACR OACR diagnosis
- ophthalmological examinations which can be performed by an ophthalmologist or in hospitals. It is based on the examination of the fundus.
- the treatment of the invention is such that a dose of between 12.5 and 25 mg / kg / day, preferably 20 mg / kg / day of hydroxycarbamide is administered to said patients. These doses are comparable to the doses used in myeloproliferative syndromes as well as in sickle cell disease. At these doses, very few adverse effects have been reported in adults and children.
- the dose administered may vary in the following cases:
- the dose of GH can be increased by 2.5 mg / kg / day.
- the treatment may be stopped temporarily and resumed at a dose of 2.5 mg / kg / day less than the previous dose.
- the treatment In case of recurrent toxicity at a dose lower than 15 mg / kg / day, the treatment must be definitively stopped.
- the administration of HC is preferably oral, which makes it easy, fast and safe for the patient.
- this mode of administration eliminates the intervention of a health professional unlike the local treatments currently used.
- the present invention therefore aims to use HC to prepare a pharmaceutical composition (or a medicament) intended to systemically treat patients suffering from CRVO (as defined above), more specifically, intended to prevent or delay increase the retinal capillary nonperfusion surface, prevent or delay the appearance of indirect signs of retinal ischemia, maintain macular thickness (or decrease it in case of macular edema), and / or maintain visual acuity in these patients.
- this composition will be intended to prevent, delay or even prevent the increase of the retinal capillary non-infusion surface so that the surface does not increase by more than 30%, preferably by more than 20%, even more preferably more than 10%, relative to the non-perfusion capillary perfusion surface before treatment.
- this composition will be intended to prevent, delay or even avoid the decline in visual acuity so that this decrease remains less than 15 letters on the ETDRS scale, preferably less than 10 letters on the ETDRS scale.
- this composition will be intended to reduce the ocular macular thickness of 100 ⁇ , preferably 200 ⁇ , even more preferably 300 ⁇ after 3 months of treatment.
- the present invention also provides a systemically administrable pharmaceutical composition (preferably orally) for use in preventing or treating OVCR patients (as defined above), more specifically, for preventing or delaying OVCR. increase in peripheral retinal capillary nonperfusion surface, prevent or delay the appearance of indirect signs of retinal ischemia, maintain macular thickness, and / or maintain visual acuity in these patients.
- This pharmaceutical composition contains, in addition to HC, at least one pharmaceutically acceptable excipient.
- pharmaceutically acceptable excipient is meant here a compound or a combination of compounds not causing side reactions and which allows for example the facilitation of the administration of the active compound, the increase of its life and / or its effectiveness in the body, the increase of its solubility in solution or the improvement of its conservation.
- pharmaceutically acceptable excipients are well known and will be adapted by those skilled in the art depending on the nature and mode of administration of the selected active compound (s).
- the dosage form of this composition is preferably an orally administrable form, for example a tablet, capsule, powder, granule, solution or oral suspension (syrup) or any form of sublingual and oral administration.
- the active ingredient (HC) can be mixed with a pharmaceutical excipient such as gelatin, starch, lactose, magnesium stearate, talc, gum arabic or analogues.
- a pharmaceutical excipient such as gelatin, starch, lactose, magnesium stearate, talc, gum arabic or analogues.
- These tablets may be coated with sucrose or other suitable materials, or may be treated in such a way that they have prolonged or delayed activity and release a predetermined amount of HC in a continuous manner.
- Capsules are obtained, for example, by mixing the active ingredient (HC) with a diluent and pouring the resulting mixture into soft or hard gelatin capsules.
- a syrup or elixir preparation may contain the active ingredient (HC) together with a sweetener, an antiseptic, as well as a flavoring agent and / or a suitable colorant.

- FA fluorescein retinal angiography
- ZAC central avascular area
- Patients enrolled in the study are persons aged at least 45 years old, of both sexes, with CRVO whose symptoms appeared less than a month before their management, and include a decrease in visual acuity with corrected visual acuity of the eye reaches less than 6/10 (73 letters ETDRS). Patients who do not meet these criteria are not included in the study. In addition, patients are excluded:
- hemoglobin ⁇ 13 g / dL (human) or ⁇ 12 g / dL (female), reticulocytes ⁇ 20000 / mm 3 , neutrophilic neutrophils ⁇ 1500 / mm 3 , platelets ⁇ 150000 / mm 3
- a doctor checks all the criteria of eligibility and non-eligibility for the protocol, collects the patient's complete clinical observation, and gives him detailed oral information and on the study, as well as the information leaflet and the consent form.
- Blood tests (a measure of NFS and serum creatinine) are also performed. These examinations form part of the usual assessment of OVCR, and make it possible to check the absence of biological criterion of non-inclusion in the study.
- D0 This is the day of inclusion of the patient in the study. That same day, after the patient has signed written consent, the following tests are performed:
- the patient also receives the hydroxycarbamide tablets to perform the first part of the treatment.
- the first dose of treatment should be made by the patient the next morning (D1), on an empty stomach.
- the treatment should then be taken daily, preferably on an empty stomach.
- the dosage form used in the present study is the SIKLOS oral form marketed by the Addmedica Laboratory in France. This medicine received a European Authorization on the 28/06/2007 for the specialty SIKLOS 1000 mg film-coated tablet in the prevention of recurrent painful vaso-occlusive attacks including that of acute thoracic syndrome in adults, adolescents and children over 2 years old with symptomatic sickle cell disease. It is an oblong, white, film-coated, trisecable tablet providing 4 equal parts of 250 mg.
- Each tablet of SIKLOS 1000 mg contains 1000 mg of hydroxycarbamide.
- the qualitative composition of Siklos 1000 mg is therefore hydroxycarbamide, sodium stearyl fumarate, silicified microcrystalline cellulose and basic butyl methacrylate copolymer.
- the patient must swallow the equivalent of 20mg / kg of the SIKLOS tablet daily for one month.
- the table below shows the dose and number of SIKLOS tablets to be taken based on the patient's body weight.
- a haematological assessment (NFS, reticulocytes) is performed, to monitor the haematological tolerance of the treatment .
- the effectiveness of the treatment with respect to the prevention of retinal non-perfusion is evaluated at D15 (S4), M1 (S13) and M6 (S26).
- the effect of treatment on visual acuity and macular thickness is evaluated at D15 (S2), M1 (S4), M3 (S13) and M6 (S26).
- M6 (S26) the incidence of irreversible rubella and neovascular glaucoma is evaluated.
- HC dose was increased by 2.5 mg / kg / day.
- the blood test performed on D0 includes the measurement of: NFS-reticulocytes, VS, CRP, TP, TCA, fibrin, electrophoresis of proteins, creatinine, lipid profile, fasting glucose, HbA1 c.
- This assessment aims to eliminate the presence of a possible haematological disorder, in particular a myeloproliferative syndrome, as well as a possible severe hepatic or renal insufficiency, constituting as many criteria of non-inclusion in the study. It also aims to clarify the patient's vascular risk factors, including diabetes and dyslipidemia.
- Fluorescein angiography is performed with a Spectralis-type scanning laser ophthalmoscope (SLO) (Heidelberg Engineering, Heidelberg, Germany) with an "ultra-wide field" objective (UWF 102).
- SLO Spectralis-type scanning laser ophthalmoscope
- UWF 102 "ultra-wide field” objective
- the patient whose pupil has been dilated beforehand, is invited to put the head on a chinrest.
- intravenous fluorescein injection is performed.
- the fundus is monitored continuously to detect the appearance of fluorescein in the retinal arteries. As soon as fluorescein appears in the retinal arteries, a high-resolution video acquisition during the whole vascular filling period (on average 10 seconds) is triggered.
- a higher magnification shot centered on the retinal avascular zone (ZAC), is made (in both eyes), then the rest of the angiogram is continued in a large field.
- the non-infusion surface is measured manually using the Spectralis measurement tools, making the ratio of the non-perfused area to the total retinal area.
- OCT consists of two sections (horizontal and vertical) centered on the fovea, as well as macular mapping.
- An OCT-angiography is also performed using the Optovue® device to evaluate the foveal capillary mesh without injection.
- the area of the central avascular zone (ZAC) is then measured using the software tools provided by the manufacturer.
- the standardized measurement of visual acuity by the ETDRS scale, internationally recognized and validated, is performed by an orthoptist (duration approximately 30 minutes). This measurement is carried out at each visit of the patients of the study.
- Tests are also performed to understand the mechanism of action of HC on retinal capillaries.
- the circulating hematopoietic progenitors are removed (2 tubes 5ml on EDTA) on day 0 and then on M3 (S13) for patients with endogenous erythroid colonies at inclusion.
- the rheological properties of red blood cells are analyzed on a LoRRca MaxSis Osmoscan Ektacytometer (Mechatronics) and a Brookfield viscometer. Several characteristics are studied: the blood viscosity, the global aggregation of red blood cells in patients' plasma, but also the characteristics of membrane stability and deformability.
- the success rate of the treatment is proportional to the percentage of patients in whom none of the following events were observed three months after the start of treatment:
- Optical coherence tomography showed macular edema and juxta-foveal hemorrhage.
- D-1 treatment the visual acuity measured on the ETDRS scale was 71 letters for the left eye and 89 letters for the right eye.
- Retinal fluorescein angiography confirmed the diagnosis of oedematous OVCR by finding a circulatory slowing of the lower hemi-vein and the absence of a non-perfusion zone.
- OCT-angiography was used to evaluate the area of the central avascular zone (CAZ) equal to 0, 12 mm 2 .
- the mean central thickness of the retinal surface was 316 ⁇ and the mean macular volume was 6.12mm 3 ( Figures 1 and 2, J-1).
- Treatment with hydroxycarbamide is started the following day as 1750 mg per day (20 mg / kg / day) of oral SIKLOS.
- follow-up visits were 13 days (S2 / D15), 27 days (S4 / M1) and 108 days (S13 / M3) after the start of treatment.
- Hydroxycarbamide was stopped for 3 days (just after the visit of S4 / M1) due to thrombocytopenia at 60000 / mm3, then resumed at a dose of 17.5 mg / kg / day. It was again stopped 1 week later for 16 days because of a hemoglobin level lowered by more than 20% compared to the pre-treatment hemoglobin level, then resumed at a dose of 15 mg / kg / day. until the visit of S13 / M3.
- the clinical tolerance of the treatment was perfect and the changes in the blood count were asymptomatic.
